(iii)in an ap given a = 4, d = 2, S = -14, find n and a. |
|
Answer» Step-by-step EXPLANATION: Given a=2. d=8 S n
=90 ⇒ 2 n
(2a+(n−1)d)=90 ⇒ 2 n
(2.2+(n−1)8)=90 ⇒ 2 n
(4+8(n−1))=90 ⇒ 2 n
(4+8n−8)=90 ⇒ 2 n
(8n−4)=90 ⇒ 2 n
(8n−4)=90 ⇒4n 2 −2n=90 ⇒2n 2 −n=90 ⇒2n 2 −n=45 ⇒2n 2 −n−45=0 ⇒2n 2 −10n−9n−45=0 ⇒2n(n−5)9(n−5)=0 ⇒(2n+9)(n−5)=0 ⇒m= 2 −9
or n=5 Hence n=-9/2 is NEGLECT since n is not negative ∴ n=5 and a n
=a+(n−1)d a 5
=a+(5−1)d =2+4.8 =2+32 =34 |

Answer» Answer: Algebra formulas are equalities which remain true regardless of the values of any VARIABLES which appear within it. In our website, we have provided two calculators for algebra formulas. One is to find the expansion for (a + b)n and other one is to find the expansion for (a - b)n. Please click the below links to get the linear REGRESSION needed. Expansion Calculator for (a + b)n Expansion Calculator for (a - b)n If you would like to have PROBLEMS on algebraic identities, please click the link given below. Worksheet on Algebraic Identities Proving Algebraic Identity Expansion Geometrically In this section, you will LEARN how to prove the expansions of algebraic identities geometrically. Let us CONSIDER algebraic identity and its expansion given below. (a + b)2 = a2 + 2ab + b2 |

9.The length of a rectangular field is 8 meters less than twice its breadth. If the perimeter ofthe rectangular field is 56 meters, find its length and breadth? |
Answer» Answer :›»› The length and breadth of a rectangular FIELD is 16 m and 12 m. GIVEN :
To find :
Solution :Let us ASSUME that the breadth of a rectangular field is x m. As it is given that, the length of a rectangular field is 8 meters less than twice its breadth. → Length = 2x - 8 m. According to the given question, As we know that → Perimeter of rectangle = 2(length + breadth). → 56 = 2(2x - 8 + x) → 56 = 2(2x + x - 8) → 56 = 2(3x - 8) → 56/2 = 3x - 8 → 28 = 3x - 8 → 28 + 8 = 3x → 36 = 3x → x = 36/3 → x = 12 Therefore, → Breadth of a rectangular field = x m. → Breadth of a rectangular field = 12 m. → Length of a rectangle field = 2x - 8 m. → Length of a rectangle field = 2 * 12 - 8 → Length of a rectangle field = 24 - 8 → Length of a rectangle field = 16 m. Hence, the length and breadth of a rectangular field is 16 m and 12 m.Verification :→ Perimeter = 2(length + breadth) → 56 = 2(16 + 12) → 56 = 2(28) → 56 = 56 Here, LHS = RHS Hence Verified ! |
